The error is:
Class 'Controller\Index' not found
but in all my code at any time I call this class:
Test.php << Script Executor
include_once("index.engine.php");
Index::importController();
use Controller\User;
echo User::getWorld(); // The error happens here.
Index.engine.php << Indexer Includes
if (!defined('HOME')) define("HOME", __DIR__."/");
class Index{
public static function importModel(){
spl_autoload_register(function ($class) {
$nome = str_replace("\\", "/" , $class . '.model.php');
if( file_exists( HOME . $nome ) ){
include_once( HOME . $nome );
}
});
}
public static function importController(){
spl_autoload_register(function ($class) {
$nome = str_replace("\\", "/" , $class . '.controller.php');
if( file_exists( HOME . $nome ) ){
include_once( HOME . $nome );
}
});
}
public static function importPersistent(){
spl_autoload_register(function ($class) {
$nome = str_replace("\\", "/" , $class . '.persistent.php');
if( file_exists( HOME . $nome ) ){
include_once( HOME . $nome );
}
});
}
}
user.controller.php << Only an intermediary
namespace Controller{
include_once (__DIR__ ."/../index.engine.php");
Index::importPersistent();
use Persistent\Test;
class User{
public static function getWorld(){
$result = Test::getEngine();
return $result;
}
}
}
user.persistent.php << Function required
namespace Persistent{
class Test{
public static function getEngine(){
$engine = "Engine is on! \o/";
return $engine;
}
}
}
Thanks for help me.
use Controller\User; # this is used to call a namespace, in your code there is no declaration of the namespace
echo User::getWorld(); //
For this, one would be expected to have a file in this form
sample.php
namespace Controller;
class User {
public static function getWorld() {
...
}
}
user.controller.php
namespace Controller{
include_once (__DIR__ ."/../index.engine.php");
Index::importPersistent();
use Persistent\Test;
class User{
public static function getWorld(){
$result = Test::getEngine();
return $result;
}
}
}
I change to:
namespace Controller{
use Index;
use Persistent\Test;
Index::importPersistent();
class User{
public static function getWorld(){
$result = Test::getEngine();
return $result;
}
}
}
The error was in the include which was called more than once, then altered to call only once in the view.

I have this file root/core/Router.php

public function getAll() {
// some code to collect data

What i want to achive is that every Controller in root/controller/*.php able to load any Model in root/model/*.php but class inside root/model/*.php must able to access (inheritance/extends) the Model class inside root/core/Model.php i firstly asked on chatGPT for some AI Generated answer, that the reason why i get this far.
Then i get this error, when the AI keep giving the same answer.
Fatal error: Cannot declare class Controller\Product because the name is already in use in C:\xampp\htdocs\app\shop\controller\Product.php on line 6
I actually realize that the simple way probably with naming the class so ther no conflict between it but i became aware how to properly using the namespace if its such features in php. Those files loaded without any autoloader, so i just require_once each file in root/init.php file.
I read few documentations but hard to implement in multiple files and directorys.
I Apreciate any feedback, thanks
I have a problem creating an object from another class inside the constructor of my kernel class, it gives a fatal error which says can not find the class, anybody can help please? I do not know what is wrong?
namespace App\Http;
use App\Http\Config;
use App\Controllers;
class kernel{
protected $controller = "HomeController";
protected $action = "index";
protected $params=[];
public function __construct(){
$url = $this->ParseUrl();
$format_url = ucfirst($url[0]) . "Controller";
if (file_exists(Config::CONTROLLERS_PATH . $format_url . ".php")) {
$this->controller = $format_url;
}
// $path = Config::CONTROLLERS_PATH . $this->controller . ".php";
// echo "path: $path";// path is correct
require_once (Config::CONTROLLERS_PATH . $this->controller . ".php");
// $include_file = get_required_files();
// var_dump($include_file);//require_once is working
//here is the problem
$this->controller = new $this->controller;
}
public function ParseUrl(){
if (isset($_GET['url'])) {
return explode("/", rtrim($_GET['url'], "/"));
}
}
}
For the setting up of a small home framework, I want to send variables to the view, but I have to date find no solutions that works.
The code in question:
src/Controller/Controller.php
<?php
namespace App\Controller;
use App\Network\Request;
class Controller {
protected $viewPath = ROOT . VIEW;
protected $template = ROOT . TEMPLATE;
protected $layout = "default";
public function __construct()
{
$request = new Request();
$this->render($request->controller().'/'. $request->action());
}
public function layout($template) {
if($template != $this->layout) {
require $this->template . $template . '.php';
}
}
public function render($view) {
ob_start();
require $this->viewPath . '/' . str_replace('.', '/', $view). '.php';
$content = ob_get_clean();
require $this->template .$this->layout . '.php';
}
public function set($varname) {
extract($varname);
return $varname;
}
}
?>
app/Controller/PostsController.php
<?php
namespace App\Controller;
class PostsController extends Controller {
public function index() {
$posts = [
"id" => "1",
"ids" => "2"
];
$this->set(compact('posts'));
}
}
?>
Using the $this->set function in PostsController returns me Undefined variable: posts after an echo.
I also try to put ob_start and ob_get_clean in the set function but do not work either.
Namely, I do not want to include the function set in render, since I handle the view of the view dynamically (see __construct ()).
Another question:
How do I associate a View class with my views and thus use $this->method ().
Thank you
Your variables are only limited to function set scope. So you cannot see it in render function
Why won't you send array of values into the render function like that
public function render($view, array $params = []){
extract($params, EXTR_OVERWRITE);
ob_start();
require $this->viewPath . '/' . str_replace('.', '/', $view). '.php';
$content = ob_get_clean();
require $this->template .$this->layout . '.php';
}
then you call it like this
$this->render('hello', [
'name' => 'Mikołaj',
'surname' => 'Woźniak'
]);
I am seeing some weird error on my client website. It's code someone else made for him for his application. The error message is saying that $this when not in object context but the Class has been extended where from App.
Please help out.

Version class loading, but var_dump show what it's empty class without function getVersion();

Methods do not show up in var_dump or print_r output, as they are not part of the state of the object. Try calling the method; it should work as expected.
